I haven't had a period since July 15th, but every test I had taken in august came back negative. I also had spotting in August so I just counted that as a period even though it really wasn't. I even went to the Health Department to make sure if I was or wasn't, it came back there with a light second line but they weren't sure so when I retested it was negative. After all that it slipped my mind, well school started back on Tuesday the 5th! I finally hit senior year! after school my mom brought up being pregnant to me because she knows I haven't had my period. I just kept saying no and didnt think anything of it. so I was going to take a test to just prove to her I wasn't and sure enough it was positive, now me and my boyfriend are looking forward to our little blessing and getting schedule fixed so I can finish high school and graduate!
